Road safety protective fence for smart city construction
The invention belongs to the field of smart cities, and particularly relates to a road safety protective fence for smart city construction. The road safety protective fence comprises bases, supporting rods and top pipes, the bases are arranged on a road isolation line at equal intervals, the supporting rods are fixedly installed on the bases, the top pipes are horizontally and fixedly connected to the upper ends of the supporting rods, each supporting rod is movably sleeved with a protective sleeve, the protective sleeve is sleeved with a buffering air bag, a cylindrical cavity is formed in the supporting rod and communicates with the buffering air bag through an air guide pipe, a piston block is slidably connected into the cylindrical cavity in a sealed mode, the lower end of the piston block is fixedly connected with a movable plate through a connecting rod, and a sliding groove is formed in the side wall of the cylindrical cavity. When a vehicle collides with the protective fence, the protective sleeve rotates and moves downwards, part of collision force of the vehicle on the supporting rod is effectively eliminated, the possibility that the protective fence is broken by collision is reduced, downward friction force is applied to the vehicle, and the vehicle is prevented from flying out upwards or turning over to cause greater harm.
本发明属于智慧城市领域，尤其是涉及一种智慧城市建设用道路安全防护栏，包括底座、支撑杆和顶管，所述底座等距排布在道路隔离线上，所述支撑杆固定安装在底座上，所述顶管呈水平固定连接在各个支撑杆的上端，所述支撑杆外活动套接有防护套管，所述防护套管外套设有缓冲气囊，所述支撑杆内设有柱形腔，所述柱形腔通过导气管与缓冲气囊连通，所述柱形腔内密封滑动连接有活塞块，所述活塞块的下端通过连接杆固定连接有活动板，所述柱形腔的侧壁上设有滑槽。本发明可在车辆撞击防护栏时，防护套管转动并向下移动，有效化解车辆对支撑杆的部分撞击力，降低防护栏被撞断的可能性，并且对对车辆施加向下的摩擦力，防止车辆向上飞出或翻车造成更大危害。
